A molecule in carrots absorbs photons of light at 455nm , What is the energy of the photon? What is the energy of one mol of these photons?

An atom in its ground state absorbs a single photon of light and then relaxes back to the ground state by emitting an infrared photon (1,200 nm) followed by an orange photon (600 nm). What is the wavelength (in nm) of the photon that was absorbed initially?

Calculate the energy of a photon of visible light with a wavelength of 677 nm.  J Calculate the energy of one mole of photons of visible light with a wavelength of 677 nm. (Note: This is the same wavelength as in the previous question).  kJ/mol

Most of the ultraviolet radiation reaching the surface of the earth is UV-A radiation, which has a wavelength range of 315 nm to 400 nm. UV-A radiation is a cause of skin aging and also contributes to development of skin cancer.Determine the energy of a mole of photons of UV-A radiation that have a wavelength of 325 nm
